Abstract

본 발명은 고에너지 밀도의 리튬이차전지용 전극 및 이를 적용한 고에너지 밀도 이차전지에 대한 것으로, 음극에는 리튬 합금이 가능한 소재를 함유하고, 양극은 가역적인 리튬 흡장 방출이 가능한 전이 금속 산화물로서, 전체 가역적인 리튬 저장능력이 양극에서 방출될 수 있는 리튬 용량보다 큰 것을 특징으로 하며, 상기 음극 및 양극 중 하나 또는 두 개의 전극 표면에 금속 리튬이 도포된 리튬이차전지용 전극 및 그 제조방법, 및 이를 포함하는 리튬이차전지에 대한 것이다. 본 발명의 리튬이차전지는 활성화 이후 금속 리튬이 잔존하지 않아 안전성이 우수하며, 단위 무게당 용량이 우수하다.
